“…The Clebsch-type decomposition, 3 the velocity field analysis in terms of a scalar and a vector potential, 4 and the stream function formulation 5 -6 are three well-known techniques, leading to an Euler equivalent system of second-order partial differential equations solved by fast iterative algorithms. Two remarkable advantages of the stream function formulation are the fast rate of convergence (because of the existing Dirichlet boundary conditions) and that of the method being conservative; whereas the main disadvantage is the nonunique determination of the static density in terms of the mass flux.…”

“…Adaptation is the process by which some aspect of the solution algorithm changes in response to an evolving solution. These changes can be in the governing equations [14], in the computational grid, or in both the equations and the grid [29]. In this thesis, adaptation refers to changes in the computational grid as the solution proceeds.…”
